Raw dry rubber is heated with sulphur (5%-8% based on the requirement), zinc oxide (a filler, 5%) and accelerator (0.5% -1%) at 400-440K for about half an hour. As the sulphur quantity increases, the rubber becomes tougher. 50% sulphur gives ebonite (vulcanite) . An accelerator containing nitroge..

Geothermal Energy - 'Geo' means earth and 'thermal' means heat. Thus geothermal energy is that heat energy obtained from hot rocks present inside the earth. This heat can be used as a source of energy to produce electricity. You know that the innermost layer of the earth is called the cor..

Geothermal Energy - Ever since the earth was formed, huge amount of heat energy has been stored in its molten core. Some of this heat is always flowing towards the surface. This heat is called Geothermal Energy. The hot interior of the earth heats up the layers of rocks above it. The wate..
